Such shells may be 5 5 'and6 of respectively difierent patterns, but formed of primarily plane sheets of metal, all inclined in parallellrelation with each othwelded or riveted at their contiguous edges. 7 er and in oblique relation to the axes of said Said casing shell 29 has semicircular re-. conduits 2 and 3. Said conduits 2 and3 have cesses 30 at itsopposite end edges,'and is prohollow, substantiallyconical, projectionsexa vided with opposite end closures 31 and 32 10 which are, conveniently, alike and formed of cast iron. Each of said closures 31 and 32 has, at its edge, a semicircularly recessed flue port 33 adapted to register with one of said casing recesses 30, and the substantially circular port thus formed is adapted to selectively register with flue fittings 3st, which are alike, and reversiblewith respect to said re: cesses and 33.

Each of saidfittings 34; has an annular flange 35 for connection with ordinary cylindrical sheet metal flue pipes, indicated respectively at 36 and 37 in Fig. I, and semicircularly recessed port openings, with edges 38 and 39 in relatively transverse planes, respectively extending parallel with, and at right angiest tne axis oit said flange 35. The construction arrangement ofsaid closures 31 and '32 and said flue fittings '34 are such that the latter maybe o'perative'ly connected with the heater casing 29 with the axes of their flanges :35 parallel with the axis of said casing 29,11s indicated at the lower portion of Fig. I, or withsucn axes extending radially at right angles to the axis o fsaid casing; as indicated at the upper portion oi-Fig. I. Said fittings 34 may be detachabl'y connected with the end c1os11i'es31 a nd-32 by screws or bolts 42.

I findit convenient to provide each of "said fittings 34 with a hand hole 4:4,1il1i1l which the -1 may be reached to remove therefrom deposits "of ash, dust, or soot, which are heat insulating. Said hol s are normally closed by caps 45, detachably secured by screws 46, or other suitable fastening means.

The eenstr u tien and arrangement abo've are such that the =connecti-on and mounting ot-such tinita ry water containers 1 and their casings in either vertical or horizontal position may be feifec-ted with the minir'nuin amount'of-l abor, in accordance with the construction, arrangement, *and-diSpositio'n of the flue pipes of the furnaces to which such heaters are aea pted to he accessory. -V-However, water containers having such characteristic teatur'e' s as above contemplated may be inclo'sed in casings of any suitable cnera'etemda tedto direct hot gaseous products of eoinbuseion with respect thereto. Moreover, s'uch flue casings as above contemplat d with flue fittings adapted for selective reversal as described, may be i'ised for any purpose for which they are adapted.
